Yellowstone Geyser Basins Quiz – Old Faithful and Steamboat

Yellowstone National Park holds about half of the world's geysers, roughly 500, clustered in geyser basins above a huge volcanic system. The Upper Geyser Basin has the densest concentration, including Old Faithful, named in 1870 for its frequent, predictable eruptions.

Norris Geyser Basin is the hottest and most changeable. Its Steamboat Geyser is the world's tallest active geyser, with major eruptions over 90 meters high, though they are unpredictable.

In Midway Geyser Basin, Grand Prismatic Spring is the largest hot spring in the US, ringed by colors from heat-loving microbes. Mud pots such as Fountain Paint Pot bubble in the Lower Geyser Basin. Visitors must stay on boardwalks, because thin crust can hide scalding water.
